N2 - A Cretaceous-Paleogene (K-Pg) succession is studied in detail in the Mudurnu-Göynük basin in northwestern Turkey. To characterize the K-Pg transition in this basin, two stratigraphic sections were measured and sampled at high resolution: the Okçular and the Göynük North sections. These sections were analysed for siderophile trace elements, including Ir and other platinum group elements (PGE: Ru, Rh, Pd, Ir, Pt), bulk stable carbon isotopes, calcareous nannofossils, planktic foraminifera and organic-walled dinoflagellate cysts (dinocysts). In this basin, the upper Maastrichtian consists of monotonous grey mudstones, mostly intercalated with turbidites and the basal Danian is characterised by grey mudstones, that are overlain by a rhythmic alternation of limetones and mudstones. The K-Pg boundary is marked by a thin, reddish ejecta layer, characterized by an enrichment of PGE and an abrupt negative shift in bulk δ
